[PATCH] dt-bindings: sram: Allow multiple-word prefixes to sram subnode

[PATCH] dt-bindings: sram: Allow multiple-word prefixes to sram subnode

[Konrad Dybcio]

From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>

Currently, foo-sram is allowed, but foo-bar-sram is not.

Allow it so that more complex names aren't unnecessarily simplified.

'|)' is an odd syntax, not really intuitive. Why this cannot be:
([a-z0-9]+-)*
?
(replacing also * -> + inside)

Yeah good idea

Although, as a fun tangent, I just checked and DTC accepts node
names starting with a hyphen.. We should probably change that..
